To connect your CITYCALL I8550 to a PlayStation 4 console, you will need to use the Remote Play feature. Here's how to do it:
Download and install the Remote Play app on your CITYCALL I8550. This app is available for both Android and iOS devices.
On your PlayStation 4 console, go to Settings > Remote Play Connection Settings > Add Device.
On your phone, open the Remote Play app and enter the code displayed on your PlayStation 4 screen.
Follow the on-screen instructions to complete the setup process.
Once the setup is complete, you will be able to use your CITYCALL I8550 to remotely control your PlayStation 4 console and play games on it. Note that you will need to be connected to the same Wi-Fi network as your PlayStation 4 console in order to use Remote Play.
It's also worth noting that not all PlayStation 4 games are compatible with the Remote Play feature. You can check the list of compatible games on the PlayStation website.
